Why did China get involved in North Korea during the Korean War?
You understand most of the conflict. Korea was divided by the Russian Communism and democratic US. The North Koreans invaded SK with the permission of the Russians. Then the UN got involved and shortly after the US. We pushed the NK forces back, and were doing incredibly well, but NK borders China. The Chinese who were communist did not like this at all. First off it made them very nervous that US forces were fighting and advancing so close to Chinese border. They were just as afraid of us as we were of them, which is why they attacked. Supporting the communist NK forces and pushed the US and UN forces far back across the 38th parallel. General Macarthur, hero of the Pacific War in WW2 wanted to use atomic weapons on the Chinese and start a major war on the Asian mainland. He was fired by Trueman for this. Most thought him crazy. So basically to answer your question. The Chinese attacked because of fear, and also to support the NK who were getting beat by democratic forces.
